TL;DR: It is proposed that in the absence of tender and mature rubber leaves, cocoa becomes the major host plant of L. tristis in rubber plantations in the Western Ghats.
Abstract: Massive seasonal invasion by the litter-dwelling beetle Luprops tristis, into residential buildings prior to monsoon rains, and their prolonged state of dormancy render them a very serious nuisance pest in rubber plantations in the Western Ghats in southern India. Feeding preferences of L. tristis towards leaf litter of seven trees co-occurring in rubber plantations, cashew (Anacardium occidentale), mango (Mangifera indica), jackfruit (Artocarpus heterophyllus), wild jack (Artocarpus hirsutus), cocoa (Theobroma cacao), cassia (Cassia fistula), sapota (Manilkara zapota) and rubber (Hevea brasiliensis) were analyzed with no-choice and multiple-choice leaf disc tests. Results showed that L. tristis is a generalist feeder with a defined pattern of preference, with the leaf litter of rubber being the most preferred followed by those of jackfruit and cocoa. Tender leaves were preferred over mature leaves except for cocoa and sapota. Equal preference towards tender and mature cocoa leaves, presence of patches of cocoa plantations and the scarce distribution of other host plants in rubber plantation belts leads to the proposal that in the absence of tender and mature rubber leaves, cocoa becomes the major host plant of L. tristis.

TL;DR: In this paper, the role of invertibility on homogeneity of a fuzzy topological space and vice-versa is investigated. And the properties of orbits in invertible fuzzy topologies are investigated.
Abstract: In this paper we study �the role of invertibility on �homogeneity of a fuzzy topological space and vice-versa. In general invertibility and homogeneity need not imply each other. However there are situations under which one implies the other. �If the invertible subspace is homogeneous, �then it is proved that the parent fuzzy topological space is also homogeneous. We also investigate the properties of orbits in invertible fuzzy topological spaces and characterize them.

TL;DR: A new carabid species, Macrocheilus devagiriensis sp.
Abstract: A new carabid species, Macrocheilus devagiriensis sp. nov., endemic to the Western Ghats is described from India. A modified key to the species from the Indian subcontinent is indicated. The categorisation of its Oriental species into five groups is also discussed.
